Answer:
58% of 121 by using 10% is 70.18.
Step-by-step explanation:
58% is about equal to 60%, or 6 times 10%. 10% of 121 is 12.1.
12.1 * 6 = 72.6
To take this further, 58% is 2% less than 60%, or 2 times 1%. 1% of 121 is 1.21.
72.6 - (1.21 * 2) = 72.6 - 2.42 = 70.18

Answer:
- time, volume
- depth, temperature
- time, plant height
Step-by-step explanation:
The axis labels answer this question. The horizontal axis is the independent variable; the vertical axis is the dependent variable.
1. Variables are time and volume.
2. Variables are depth and temperature.
3. Variables are time and plant height.
Answer:
rise over run is 1/4
Step-by-step explanation:
Here, we want to calculate the ratio of the rise to the run
Mathematically, this is simply referring to the slope
To get the slope, we need to select any two points and then apply the slope formula
The two points selected are;
(8,-6) and (-4,-9)
The slope formula is;
m = (y2-y1)/(x2-x1) = (-9 -(-6))/(-4-8) = -3/-12 = 1/4
The answer is option B. Hope this helps:)
Answer: The total volume of the the cubes in the tower is 792 cubic centimetres (792 cm³)
Step-by-step explanation: We shall call the volume of the cube at the bottom VB, the volume of the cube at the middle VM, and the volume of the cube at the top VT. The tower is made up of cubes at different levels and at the bottom the cube measures 8 centimetres. The cube at the middle measures 2 cm less than the bottom cube, hence middle cube equals 8 minus 2 which equals 6 cm. The top cube measures 2 cm less than the middle cube, hence the top cube equals 6 minus 2 which equals 4 cm. The volume of each cube is given as;
Volume = L³
The length of a cube measures the same on all sides, that is, length, width and height. The length on all sides therefore of the bottom cube is 8 cm. The volume equals;
VB = 8³
VB = 512 cm³
The length on all sides of the middle cube is 6 cm (measures 2 cm shorter than the bottom cube). The volume of the middle cube equals;
VM = L³
VM = 6³
VM = 216 cm³
The length on all sides of the top cube is 4 cm (measures 2 cm shorter than the middle cube). The volume of the top cube equals;
VT = L³
VT = 4³
VT = 64
From the calculations shown, the total volume of the cubes in the tower is given as;
Total volume = VB + VM + VT
Total volume = 512 + 216 + 64
Total volume = 792 cm³
Total volume is 792 cubic centimetres.
